jup. the header is present and correct.

seems so. so how cold i fix this problem? we get almost once a day spam
with forged headers and its not so easy to restrict it via SMTP cause
some users of rt also send themselves mails out with a role-acount's
email address. we investigated the problem and found that the mail loop
stops when we take out the ``requestor'' as ``watcher'' on those tickets..
but it takes some while to find out what is the _corrupt_ ticket.

i think the problem is somewhere with the ``notify_all_watchers'' function
of rt2 ... (as far as i know a requestor is also a watcher - but there 
should be a check within rt2 to prevent a loop here, or?)

later,
cjm
